Why Volkswagen Jetta Cruise Control Not Working

Throttle Position Sensor

Cruise Control Switch

The cruise control switch is a mechanical switch that tells the car’s computer to engage or disengage the cruise control. If the switch is faulty, the cruise control will not work.

Cruise Control Servo

The cruise control servo is a motor that controls the throttle linkage. If the servo is faulty, the cruise control will not be able to move the throttle and the cruise control will not work.

Cruise Control Wiring

The cruise control system is controlled by a series of wires. If any of these wires are damaged or disconnected, the cruise control will not work.

How to Troubleshoot: Volkswagen Jetta Cruise Control Not Working

The cruise control on your Volkswagen Jetta is a convenient feature that can help you maintain a steady speed on long road trips. However, if your cruise control isn’t working properly, it can be a real pain. There are a few different things that could be causing the problem, and it’s usually pretty easy to troubleshoot.

In this article, we’ll walk you through the steps to troubleshoot a Volkswagen Jetta cruise control that’s not working. We’ll cover everything from checking the fuses to replacing the cruise control switch. By the end of this article, you’ll be able to get your cruise control working again in no time.

Step 1: Check the fuses

The first thing you should do is check the fuses for the cruise control system. The fuses are located in the fuse box under the hood.

To check the fuses, you’ll need a fuse puller. You can find these at most auto parts stores.

Once you have the fuse puller, open the fuse box and locate the fuses for the cruise control system. The fuses are usually labeled cruise control or CC.

Pull each fuse out of its socket and inspect it for damage. If the fuse is blown, it will be blackened or melted.

If a fuse is blown, replace it with a new fuse of the same amperage.

Once you’ve replaced the fuse, start your car and try the cruise control again. If the cruise control is still not working, move on to the next step.

Step 2: Check the cruise control switch

The next thing you should check is the cruise control switch. The cruise control switch is located on the steering column.

To check the switch, you’ll need a voltmeter. You can find these at most auto parts stores.

With the ignition on, connect the voltmeter to the cruise control switch.

Turn on the cruise control. The voltmeter should show a reading of 12 volts.

If the voltmeter doesn’t show a reading of 12 volts, the cruise control switch is bad and needs to be replaced.

Once you’ve replaced the cruise control switch, start your car and try the cruise control again. If the cruise control is still not working, move on to the next step.

Step 3: Check the cruise control actuator

The cruise control actuator is a motor that controls the throttle valve. It’s located under the hood, near the throttle body.

To check the actuator, you’ll need a multimeter. You can find these at most auto parts stores.

With the ignition on, connect the multimeter to the actuator.

Turn on the cruise control. The multimeter should show a reading of 12 volts.

If the multimeter doesn’t show a reading of 12 volts, the actuator is bad and needs to be replaced.

Once you’ve replaced the actuator, start your car and try the cruise control again. If the cruise control is still not working, move on to the next step.

Step 4: Check the cruise control computer

The cruise control computer is a module that controls the cruise control system. It’s located under the dash.

To check the computer, you’ll need a Volkswagen Jetta scan tool. You can find these at most auto parts stores.

With the scan tool, you can check the codes for the cruise control system. If there are any codes, they will tell you what’s wrong with the system.

If the computer is bad, it will need to be replaced.

Once you’ve replaced the computer, start your car and try the cruise control again. If the cruise control is still not working, you may need to take your car to a Volkswagen dealer for further diagnosis.

Conclusion

Troubleshooting a Volkswagen Jetta cruise control that’s not working can be a bit tricky, but it’s usually pretty easy to do if you follow the steps in this article. By following these steps, you can get your cruise control working again in no time.
